# B550 suspend bug
|
||
|
|
|
||
|
|
Gigabyte B550-family motherboards have a hard to diagnose (At least, from the system log events) suspend bug.
|
||
|
|
|
||
|
|
As of the F18 bios for the b550m-d3sh (My machine), released in 2024-02-27, this is still unfixed by the manufacurer and has been for over 4 years.
|
||
|
|
|
||
|
|
Symptoms:
|
||
|
|
- Suspend PC
|
||
|
|
- It goes into suspend, then seems to boot and hang. Sometimes it suspends successfully, but waking it from suspend puts it in the "zombie" state.
|
||
|
|
- By playing chicken with volatile storage and flicking the power switch on the back of power supply, you can sometimes get it to wake from suspend as the card un-powers before volatile storage does.
|
||
|
|
|
||
|
|
Fix: disable GPP0 and GPP8 (And, for some cards, potentially PTXH, I can't test) in /proc/acpi/wakeup
|
||
|
|
- To do this permanently, a systemd service is provided
|
||
|
|
